HAY-RAKE.

Application filed January 27, 1911.

To all whom it may concern:

Be it known that we, Josnrrr F. GREEK, residing in the city of PaloAlto, county of Santa Clara, State of California, and learns S.VVIIHERELL, residing at Stanford University, in said county and State,and both citizens of the United States, have jointly invented a new anduseful Improvement in Hay-Rakes, of which the following is aspecification, reference being hereby made to the accompanying drawing,forming a part hereof.

This invention relates to a hay rake of the wheelless type in which thehorses drawing the rake walk on either side and in advance of the raketeeth. This style of rake is usually employed in forming windrows of hayinto cocks.

The primary object of this invention is to provide a hay rake of a wellknown type with a mechanical device by means of which the tractive forceis rendered operative for dumping the rake, with a minimum of effort onthe part of the operator.

The invention will be more fully eX- plained hereinafter with referenceto the accompanying drawings in which it is illustrated and in whichFigure 1 is a plan view of a hay rake embodying the features of theinvention. Fig. 2 is a side view of the rake. That portion drawn in fulllines shows the mechanism in proper adjustment for dragging the rakealong the ground, and the dotted portion shows the rake and mechanism inthe act of dumping. Fig. 3 is a partial end view of the rake. Fig. 4- isa rear view of one end of the rake and shows the relationship of thelatch and dumping mechanism.

A is the body of the rake and to it are rigidly attached the rake teethE B, the posts C O and the handles D D. E is a crossbar bolted to theteeth to brace them. These foregoing are generally made of wood and formthe essential parts of a hay rake of this type. Several minor details,such as reinforcing straps, bolts and screws, which are not required fora correct understand ing of this invention, have been omitted. Under theheels of two or more of the teeth are fastened shoes F F, and withinconvenient reach of the operator are foot rests G G.

H H are arms integral with shafts I I, which are pivotally attached tothe rear of Specification of Letters Patent.

timber A by means of bearings J J, and are kept from lateral movement bythe pins K K. On the inner sides of the arms H H are securely fastenedlugs L L.

M M are latch bolts sliding in bearings O O which are fastened to thetop of timber A. Bolts M M are operated by means of pressure upon thefoot lever W, connection thereto being made by flexible cords, cables orchains Q Q which run over pulleys R R.

X is the fulcrum of the lever When the pressure upon the foot lever isremoved, the bolts are returned into place by the springs S S.

N N, are clevises which form the connection between the cords Q Q andthe latch bolts M M.

P P are pins attached to A and act as stops to prevent the bolts M Mfrom being pulled back too far.

T T are links to which the horses are hitched, and are pivotally boltedto the arms H H by bolts U U which are inserted in the holes V V. Whenthese bolts are placed in those holes farthest from the fulcrum, theleverage exerted by the pull of the horses is greatest.

. The movement of the arm H relative to the rake is limited to the twoextremes shown in Fig. 3. In its normal position, iridicated by the fulllines, it is held by the latch bolt M. hen the latch is withdrawn, thearm cannot fall back because its bent portion still engages the front ofthe bolt. It is, however free to swing upward to the vertical positionindicated by the dotted lines, where it is stopped by the contact of thelug L against the latch bolt M.

WVhen being used, the rake is drawn along the ground in the positionshown by the full line portion of Fig. 2, the arms H H being locked innormal position. With the mechanism in this position, the rake drawnalong a windrow of hay. Should the rake teeth catch in the ground andinterfere with the work, the operator may raise them clear of the groundby standing upon the foot rests G G, the shoes F F acting as fulcrums.WVhen a suficient amount of hay has been gathered, it becomes necessaryto dump the rake, leaving the load in a pile.

By the use of our invention, the second man is dispensed with. When thedriver wishes to dump, he presses upon the foot lever W thus trippingthe latches M M and releasing the arms H H. The horses pull these armsforward and upward to the ver tical position shown in Fig. 8, where afur ther pull results in tilting the rake forward, digging the raketeeth BB into the ground. As soon as the teeth engage the ground, therake begins to overturn as indicated by the dotted line portion of Fig.2, and the dumping is completed as in the previous case, the

rake rolling completely over, until the teeth again project horizontallyforward. lVhile the rake is turning over, the arms swing back to theirnormal posit-ion, the latch bolts springing into place automatically.

One important feature of our invention is its applicability to hay rakeswhich are already in use, it being unnecessary to purchase a new rake toenjoy the benefit of this invention.

lit is obvious that a hand lever would opcrate the latch equally welland also that a different form of latch and stop could be employed tohold and release the draft shifter arm.

It will be understood that the details of construction andarrangei'nentmay be varied as may be required or desirable for differentconditions of use.

Having thus described the nature of our invention, its object and themanner of its operation, we claim as new the following 1. Thecombination with a hay rake capable of progressive movement and of anoverturning movement, of means for applying a tractive force thereto ata predetermined point for obtaining the progressive movement and forshifting said tractive force to a different point to effect theoverturning movement.

2. The combination with a hay rake capable of progrcs ive movement andof an overturning movement, of a device to which the tractive force isapplied, said device being movable to different positions on thevehicle, in one of which the progressive movement of the vehicle isobtained and in another of which the overturning movement is secured,and means for controlling the position of the device.

3. The combination with a hay rake of the wheelless type of a pivotallyattached arm to which the tractive force is applied, a ful-' crum forsaid arm, means for holding the arm in an approximately horizontalposition for the purpose of moving the rake, means for releasing thearm, and means for holding the arm in an approximately vertical positionfor the purpose of enabling the tractive force to overturn the rake.

4-. The combination with a hay rake capable of progressive movement andof an overturning movement, of an arm pivoted to the vehicle and towhich the tractive force is applied, said arm being movable to oneposition in which the progressive movement of the vehicle is obtainedand swinging to another position in which the overturning movement issecured, and means for controlling the position of the arm.

5. The combination with a hay rake capable of being overturned of apivotally attached arm to which the tractive force is applied, a fulcrumfor said arm, means for holding the arm in an approximately horizontalposition for the purpose of moving the rake, means for releasing thearm, and means for holding the arm in an approximately vertical positionfor the purpose of enabling the tractive force to overturn the vehicle.

6. The combination with a rake, of an arm pivoted to the rake, a draftdevice connected to the arm at one side of its pivot, means for normallyholding the arm in a position to cause the progressive movement of therake when tractive force is applied to the draft device, said arm beingmovable to a different position to cause the overturning movement of therake when released from the holding means, and a stop for limiting themovement of the arm to the overturning position.
